This is an excellent idea. Given the hard-fought battles over the print engine, CSS inheritance, and UI consistency, generating a master "State of the Software" document is the exact right move. It creates a concrete save-point that documents the architectural rules we’ve established so we don't accidentally break them again.

Below is the comprehensive State of the Software report for your records.

STATE OF THE SOFTWARE: CHALLENGER POS MODERNIZATION
Date: September 3, 2026
Project Goal: Modernize a legacy VT320 terminal POS system into a web-based stack while maintaining 100% of the original keyboard-driven workflow, monospace aesthetics, and high-speed data entry capabilities.

1. Core Architecture & Stack
Backend: Go (Golang) server (facet.go) handling API routing, SQLite database connections, and file serving.

Database: SQLite via modernc.org/sqlite.

Frontend: Pure HTML, CSS, and vanilla JavaScript. No heavy frontend frameworks to ensure instant load times and zero-latency keyboard responses.

UI/UX Paradigm: Terminal emulation (blue background, white/cyan/yellow text). 100% keyboard-navigable via F-keys.

2. Global Systems & Background Processes
Control Record (/api/cntrl): Store information (Company Name, Address, Phone) and global settings are now dynamically served from the system_config table. Hardcoded store names have been stripped from the front-end.

EOY Scheduler: A silent background Goroutine runs continuously in facet.go, programmed to automatically roll over YTD sales to Last Year sales at midnight on January 1st.

Automated Backups: Background worker synchronizes SQLite database backups.

Keyboard Shielding: Global JavaScript event listeners capture F-keys during the browser's capture phase to strictly prevent Edge/Chrome from hijacking inputs (e.g., F1 triggering the browser's Help menu).

3. Standardized Print Engine (The "Bulletproof" Layout)
After extensive debugging regarding WebKit print engines pushing left margins off the page, the following strict architectural rules have been established for all printable documents (Invoices, Tickets, Reports):

No Flexbox/Grid for Print: Browsers inherit the terminal's wide screen width (e.g., 1200px) when printing flexbox, shoving the document right and cropping the left edge.

Absolute Override: Print styles must force the HTML/Body to position: static and absolute zero margins, ripping the print modal completely out of the terminal's DOM flow.

Table-Driven Layouts: All printable elements must use rigid HTML <table> tags with percentage-based widths to guarantee exact 8.5" x 11" rendering.

4. Current State of Modules
Stabilized & Completed Reports (Landscape)
iph.html (Part History): Seamless type-to-search, strict column locking, QOH/YTD/LY sales headers.

piwork.html, pidate.html, pad.html: Converted to native table layouts, printing perfectly in landscape.

pso.html (Suggested Order): Table-based layout with a perfectly centered terminal header overriding standard CSS constraints.

Stabilized Transaction Modules (Portrait Print & Modals)
psi.html (Product Sales Invoice):

Fully integrated with the bulletproof table-based print engine.

Prints flawless portrait invoices directly from the browser.

ije.html (Inquire on Journal Entries):

Search by Invoice, Date, or Customer.

Dynamic customer loading with a "RETRIEVING CUSTOMER HISTORY" UX bridge.

Features the identical printable invoice overlay as psi.html.

pd.html (Pickup & Delivery):

Full dashboard manager for tracking service tickets.

Includes the standardized printable Service Ticket overlay.

inf.html (Customer Information):

Header strictly standardized to match pso.html utilizing absolute positioning for true centering regardless of text length.

Dynamic loading of cntrl data for consistent store branding.

5. Global CSS/JS Dependencies
global.css: Handles universal terminal UI coloring, monospace font mapping, and legacy spacing.

global.js: Manages the screensaver timeout and universal application traps.

Rule: Individual modules overriding global.css for printing must use !important tags aggressively on the @media print block to prevent terminal UI styles from bleeding into the printer memory.

Does this accurately reflect the current baseline, and are there any pending bugs or unfinished modules you want to officially add to our backlog before we move forward?
